WESLEY T. HAZELRIGG, OF EL DARA, ILLINOIS.

ENSILAGE-PACKER.

Application filed September 1, 1916.

To all whom it may concern:

Be it known that I, VVEsLnY T. HAZEL- nrco, a citizen of the UnitedStates, residing at El Dara, in the county of Pike and State ofIllinois, have invented certain new and useful Improvements in Ensilage-Packers; and 1 do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to a packer for packing ensilage in silos and theprimary object of the invention is to provide a rotary packer which ismounted interiorly of a silo and forced upwardly by the ensilage withwhich the silo is filled.

A further object of this invention is to provide an ensilage packer asspecified which includes specifically, a vertical shaft having a castingattached to the lower end of the same to which a plurality of packingrollers are swivelly connected, to provide a bevel gear structurecarried by the upper end or top of the silo through the medium of whichthe vertical shaft is rotated, and further to provide a pair of rollerswhich are rotatably supported interiorly of the bevel gear for rotatingthe vertical shaft and also! for permitting the shaft to move verticallythrough the bevel driving gear.

With the foregoing and other objects in view this invention consists insuch novel features of construction, combination and arrangement ofparts as will be hereinafter more fully described, illustrated in the accompanying drawings and claimed.

In describing the invention in detail reference will be had to theaccompanying drawings wherein like characters designate like andcorresponding parts throughout the several views, and in which Figure 1is a vertical section through a silo showing the improved tamper appliedthereto.

Fig. 2 is a horizontal section through the silo.

Fig. 3 is a vertical section through the tamper structure.

Fig. i is a vertical section through the driving bevel gear, and

Fig. 5 is a horizontal section on the line of Fig. 4.

Referring more particularly to the drawings, 1 indicates a silo of anyordinary construction which has a beam 2 supported by Specification ofLetters Patent.

about the sprocket 5 and about a sprocket 7 carried by a shaft 8. Theshaft 8 is supported in any suitable manner by the silo structure 1 andit has a pulley 9 mounted thereon which may be connected to any suitabletype of a prime mover for transmitting power to theshaft 8 and to theshaft 4 through the medium of the sprocket chain 6 and the sprockets 5and 7.

The shaft 4: has a bevel gear 10 mounted thereon which meshes with abevel gear 11. The bevel gear 11 is rotatably supported by the beam 2 asclearly shown in Fig. 4; of the drawings, and it is held againstvertical displacement by means of a nut or collar 19, which is mountedupon the hub 13 of the bevel gear. If it is so desired, suitable bearingrollers indicated at la may be provided for relieving the friction ofthe rotary movement of the bevel gear 11. The bevel gear 11 is providedwith a central bore 15 through which a vertical shaft 16 extends. Theshaft 16 is substantially oval shaped as clearly shown in Figs. 2 and 5of the drawings, and it has a casting 17 mounted upon its lower end. A.plurality of packing rollers 18 are swivelly connected as shown at 19 tothe casting 17. In the drawings, the packing or tamping rollers 18 areillustrated as conical in shape, but it is to be understood that anydesired or practical shape of roller may be employed without departingfrom the spirit of this invention.

The outer end of the rollers 18 are re- 0 cessed as shown at 19 so as toprovide for the increasing of the length of the rollers by the additionof sections as indicated at 20. The sections :20 are provided withreduced portions 21 which are externally screw threaded as shown at 22and are adapted for connect-ion with the internal screw threads 23formed about the inner wall of the re cess 19'.

The shaft 16 is slidably mounted in the bore 15 of the bevel gear 11 sothat it may move vertically therethrough and a pair of rollers 25 and 26are rotatably carried by the bevel gear 11 and engage the edges of theshaft 16 as clearly shown in Fig. 5 of the drawings, for rotating theshaft by the rotation of the bevel gear, and also for permitting theshaft to move vertically through the bore 15 of the bevel gear 11, sothat the rollers 18 may ride upon the top of the ensilage Which is beingfed into the silo l, at all times.

The packing or tamping rollers 18 are preferably rotatably mounted uponrods 28 Which are connected to the casting 17 at the point 19.

From the foregoing description taken in connection With the accompanyingdrawings, the advantages of construction, and of the method of operationof the improved ensilage packer will be readily apparent to thoseskilled in the art to Which this invention appertains.

shaft extending through said bevel gear, a pair of rollers rotatablymounted Within said bevel gear and'engaging said vertical shaft forrotating the shaft upon rotation of the otally connected to saidcasting, the outer 5 ends of said packing rollers being provided Withrecesses, sections adapted for connection to the outer recessed ends ofsaid packing rollers for increasing their length and Weight.

In testlmonywhereof I afliX my signature in presence of tWo Witnesses.
